Oregon does not allow common law marriages to be formed within the state, but courts will recognize and dissolve valid common law marriages established in other states under the Full Faith and Credit Clause. If you entered a common law marriage in Colorado, Texas, Kansas, Iowa, Montana, Oklahoma, Utah, or the District of Columbia, Oregon circuit courts have full authority to grant a divorce with the same $287-$301 filing fee and equitable distribution principles applied to all Oregon dissolutions. Couples who cohabitated in Oregon without a valid out-of-state common law marriage have no divorce rights and must resolve property disputes through contract law, with median litigation costs of $15,000-$30,000.

Oregon Does Not Create Common Law Marriages
Oregon is one of 13 states that has never recognized common law marriage formation within its borders. No amount of cohabitation time, regardless of whether you lived together for 5 years, 20 years, or longer, creates a legal marriage in Oregon. Under Oregon law, a valid marriage requires obtaining a marriage license from a county clerk and solemnizing the marriage before an authorized officiant per ORS 106.150. Without these formal requirements, couples remain legally unmarried with no automatic property division rights upon separation.
This distinction carries substantial financial consequences. Married couples divorcing in Oregon benefit from equitable distribution under ORS 107.105(1)(f), which presumes both spouses contributed equally to property acquired during marriage. Unmarried cohabitants must instead prove ownership through title documents, written agreements, or implied contracts, with the burden of proof falling entirely on the claimant. The Oregon Supreme Court established in Beal v. Beal, 282 Or. 115 (1978), that courts should distribute property of unmarried couples based on express or implied intent, but this requires expensive litigation averaging $15,000-$30,000 to resolve compared to typical uncontested divorce costs of $1,500-$5,000.
Divorcing a Common Law Marriage from Another State in Oregon
Oregon circuit courts will grant divorces for valid common law marriages established in the eight jurisdictions that currently recognize them: Colorado, Texas, Kansas, Iowa, Montana, Oklahoma, Utah, and the District of Columbia. Under the Full Faith and Credit Clause of the U.S. Constitution, Oregon must respect marriages validly formed in other states, even though Oregon itself does not allow common law marriage formation. The divorce process follows identical procedures to any Oregon dissolution, with the same filing fees of $287-$301 and equitable distribution principles.
Requirements to Prove Your Out-of-State Common Law Marriage
Before Oregon courts will dissolve your common law marriage, you must establish that a valid marriage existed under the originating state's law. Courts typically require documentation including affidavits from both parties, third-party witness statements, joint tax returns filed as married, shared bank account records, insurance beneficiary designations, and evidence you held yourselves out publicly as spouses. The specific requirements vary by originating state:
| State | Key Requirements | Evidence Needed |
|---|---|---|
| Colorado | Mutual intent + conduct as spouses | Third-party affidavits, joint accounts, tax returns |
| Texas | Agreement + cohabitation + public representation | Declaration of Informal Marriage or witness testimony |
| Kansas | Present-tense agreement + cohabitation + holding out | Both parties age 18+, written statements |
| Iowa | Intent + continuous cohabitation + public declaration | Joint property, shared finances documentation |
| Montana | Mutual consent + cohabitation + reputation | No minimum duration, community recognition |
| Oklahoma | Agreement + cohabitation + holding out | Both competent, not already married |
| Utah | Consent + legal capacity + cohabitation + public reputation | Court or administrative order recommended |
| District of Columbia | Agreement + cohabitation + community recognition | No ceremony required, witness testimony |
Texas offers a streamlined proof method through the Declaration of Informal Marriage, which can be filed with any county clerk for approximately $46 and provides official documentation of the marriage. Colorado courts look at the totality of circumstances under the framework established in In re Marriage of Hogsett & Neale, 478 P.3d 713 (2021), examining factors like shared last names, joint finances, and referring to each other as spouses.
Oregon Residency Requirements for Common Law Divorce
Under ORS 107.075, Oregon applies a two-tier residency requirement depending on where your marriage (including common law marriage) was formed. If the common law marriage was established in Oregon (which is legally impossible, so this scenario applies only to ceremonial marriages performed here), either spouse may file immediately without any waiting period. If the common law marriage was established outside Oregon (the only possibility for common law marriages), at least one spouse must have resided in Oregon continuously for 6 months before filing.
Residency can be established through an Oregon driver's license, voter registration, utility bills in your name, lease or mortgage documents, state tax returns showing an Oregon address, or employment records. Non-immigrant alien status does not prevent establishing Oregon domicile for dissolution purposes. Once residency is established, you may file in the circuit court of any county where either spouse resides.
Filing Fees and Court Costs
The Oregon circuit court filing fee for dissolution of marriage is $287 effective January 1, 2026, under ORS 21.155, though some counties charge up to $301. Beyond the initial filing fee, expect additional costs including process server fees ($30-$150), certified copies of the judgment ($5-$25 each), parent education classes if children are involved ($60-$100 per person), and mediation fees if ordered ($100-$300 per hour).
Fee waivers are available for petitioners whose household income falls at or below 125% of the federal poverty level, which is $19,506 for a single person in 2026. Recipients of SNAP, TANF, or SSI benefits also qualify. With a fee waiver, your only out-of-pocket cost is typically $50-$150 for service of process.
Total Cost Breakdown
| Divorce Type | Estimated Cost Range |
|---|---|
| Uncontested (self-filed) | $301-$500 |
| Uncontested (with attorney) | $1,500-$5,000 |
| Contested (average) | $15,000-$30,000 |
| Contested (complex, high-asset) | $50,000+ |
| With fee waiver | $50-$150 (service only) |
As of May 2026, verify the exact filing fee amount with your local circuit court clerk before filing.
Property Division in Common Law Divorce
Oregon applies equitable distribution principles to all divorces, including those dissolving out-of-state common law marriages. Under ORS 107.105(1)(f), courts divide property as may be just and proper in all the circumstances, with a rebuttable presumption that both parties contributed equally to property acquired during the marriage. This presumption treats homemaker contributions as equal to financial contributions, meaning a spouse who did not work outside the home still receives equal consideration.
Equitable distribution does not necessarily mean 50/50. Courts weigh factors including marriage length, each spouse's earning capacity, financial and non-financial contributions, tax consequences of the proposed division, children's needs, and the health of both parties. Oregon is a pure no-fault state, so marital misconduct plays no role in property division. For long marriages (typically 10+ years), courts generally award near-equal splits, though divisions of 60/40 or other ratios are possible based on specific circumstances.
Separate vs. Marital Property
Marital property includes all assets and debts acquired during the common law marriage, regardless of which spouse's name appears on the title. Separate property, including assets owned before the marriage, inherited property, and gifts received individually, is generally excluded from division. However, if separate property was commingled with marital assets or significantly appreciated due to either spouse's efforts during the marriage, courts may include some or all of it in the equitable distribution.
Retirement accounts and pensions are explicitly classified as divisible property under ORS 107.105. ERISA-governed plans require a Qualified Domestic Relations Order (QDRO) for division, while Oregon PERS accounts use separate division forms specific to state retirement systems.
No Common Law Marriage Alternative: Property Rights for Unmarried Couples
Couples who cohabitated in Oregon without a valid common law marriage from another state cannot file for divorce and have no automatic property rights upon separation. Oregon law treats unmarried cohabitants fundamentally differently than married couples, with property belonging to whoever holds title unless there is a written agreement or the other party can prove an implied contract.
The Oregon Supreme Court's Beal v. Beal decision established that courts should distribute property of unmarried couples based on express or implied intent, but this requires litigation. Without a written or oral agreement, courts examine the intent of the parties regarding each asset and liability. This process typically costs $15,000-$30,000 in attorney fees and court costs, compared to $1,500-$5,000 for an uncontested divorce with an attorney.
No Spousal Support for Unmarried Partners
Unlike married couples dissolving through divorce, unmarried partners in Oregon have no legal right to spousal support (alimony) upon separation. This distinction applies regardless of relationship length or financial disparity between partners. A partner who sacrificed career advancement to support the household receives no automatic compensation under Oregon law if the couple was never legally married.
Registered Domestic Partnerships in Oregon
Oregon offers registered domestic partnerships as an alternative to marriage under ORS 106.300 through ORS 106.340. Under the Oregon Family Fairness Act, a registered domestic partnership is a civil contract between two individuals who are at least 18 years old, otherwise capable of marriage, and with at least one partner being an Oregon resident. Importantly, only same-sex couples can currently file for registered domestic partnerships in Oregon.
Under ORS 106.340, any privilege, immunity, right, or benefit granted to a married individual extends on equivalent terms to an individual in a domestic partnership. This includes authority to make medical decisions, inheritance protections without a will, and access to dissolution procedures identical to divorce. Partners in a domestic partnership who wish to separate must file for dissolution through the circuit court, following the same process and paying the same $287-$301 filing fee as married couples.
Dissolution of Domestic Partnerships
Each individual who signs a Declaration of Domestic Partnership automatically consents to Oregon circuit court jurisdiction for dissolution proceedings, even if one or both partners later move out of state. The petition may be filed in the county where either partner last resided. Property division follows the same equitable distribution principles as divorce, and partners cannot file a new Declaration of Domestic Partnership or enter a marriage with someone else until a dissolution judgment is entered.
Cohabitation Agreements: Protecting Unmarried Couples
For unmarried couples who cannot establish a common law marriage (the vast majority in Oregon), a cohabitation agreement provides crucial legal protection. Similar to a prenuptial agreement, a cohabitation agreement is a written contract that outlines each partner's rights and responsibilities regarding property ownership, financial obligations, and procedures for dividing assets if the relationship ends.
A comprehensive cohabitation agreement typically addresses joint property purchases (especially real estate), shared bank accounts and investments, debt responsibility, household expense allocation, business interests, and separation procedures. Attorney fees for drafting a cohabitation agreement typically range from $500-$2,500 depending on complexity, a fraction of the $15,000-$30,000 average cost of litigating property disputes without an agreement.
States That Recognize Common Law Marriage (2026)
Only eight jurisdictions currently allow new common law marriages to be formed. If you established a common law marriage in one of these locations before moving to Oregon, Oregon courts will recognize your marriage for divorce purposes:
| Jurisdiction | Key Requirements | Special Notes |
|---|---|---|
| Colorado | Mutual intent + conduct as spouses | No minimum cohabitation period |
| Texas | Agreement + cohabitation + public representation | Declaration of Informal Marriage available ($46) |
| Kansas | Present agreement + cohabitation + holding out | Both parties must be 18+ |
| Iowa | Intent + continuous cohabitation + public declaration | No specific duration required |
| Montana | Mutual consent + cohabitation + reputation | Recognized since territorial days |
| Oklahoma | Agreement + cohabitation + holding out | Both parties competent and unmarried |
| Utah | Consent + legal capacity + cohabitation + reputation | Court or administrative validation recommended |
| District of Columbia | Agreement + cohabitation + community recognition | Federal district, not a state |
Several states previously recognized common law marriage but no longer allow new formations: Alabama (ended 2017), Georgia (ended 1997), Pennsylvania (ended 2005), South Carolina (ended 2019), Florida (ended 1968), Indiana (ended 1958), and Ohio (ended 1991). Common law marriages validly established in these states before their cutoff dates remain legally valid and would be recognized by Oregon courts.
Timeline for Common Law Divorce in Oregon
Oregon eliminated its 90-day waiting period in 2011, meaning divorce can finalize immediately upon the judge signing the judgment if all issues are resolved. However, realistic timelines depend on case complexity:
| Scenario | Typical Timeline |
|---|---|
| Uncontested (all issues agreed) | 30-90 days |
| Contested (negotiated settlement) | 6-12 months |
| Contested (trial required) | 12-24 months |
| Complex (high assets, custody disputes) | 18-36 months |
For common law divorces specifically, additional time may be needed to establish that a valid common law marriage existed under the originating state's law. This proof process can add 1-3 months if documentation is readily available, or 6+ months if contested.
